The Difference Between Gasoline Engine Oil and Diesel Engine Oil

[DeJasmine]

Gasoline engine oil and diesel engine oil differ in the following aspects: 1. Volatility: Gasoline is highly volatile, whereas diesel is difficult to volatilize. Therefore, gasoline vehicle pollutants include fuel evaporation emissions, the components of which are hydrocarbons. 2. Mixing: Gasoline easily mixes with air and remains stable once mixed. Gasoline and air can mix uniformly, with virtually no localized over-concentration or under-concentration or liquid oil droplets. Gasoline molecules are smaller. Diesel and air mix unevenly, inevitably leading to localized oxygen deficiency or excess. When fuel is exposed to high temperatures and oxygen deficiency, it tends to carbonize and form soot. Diesel combustion produces some odorous organic gases, hence diesel engine emissions also have a distinct smell.
